Need help with /etc/hdparm.conf

[Eric Potter]

I have a problem that my first hdd always boots up with dma off.
So I have modified /etc/hdparm.conf to include as follows:

/dev/hda {
        dma = on
}

However this is not executed during boot up.  dmesg shows this:

md: md driver 0.90.0 MAX_MD_DEVS=256, MD_SB_DISKS=27
hdb: dma_intr: status=0x51 { DriveReady SeekComplete Error }
hdb: dma_intr: error=0x84 { DriveStatusError BadCRC }
hdb: dma_intr: status=0x51 { DriveReady SeekComplete Error }
hdb: dma_intr: error=0x84 { DriveStatusError BadCRC }
hdb: dma_intr: status=0x51 { DriveReady SeekComplete Error }
hdb: dma_intr: error=0x84 { DriveStatusError BadCRC }
hdb: dma_intr: status=0x51 { DriveReady SeekComplete Error }
hdb: dma_intr: error=0x84 { DriveStatusError BadCRC }
hda: DMA disabled
ide0: reset: success

I can turn on dma manually after booting.
